Should I Close My Crawl Space Vents During Winter?

In short the answer is generally yes, they should be closed up during the
winter months. If you follow a typical Monthly Maintenance Schedule, Preferred
Pest Termite and Turf recommend the month of October in East Tennessee
as a good time to do this.

There are a couple of reasons for this with the first being you want to
prevent frozen water lines and/or snow from entering. The second biggest
issue has to deal with stack effect. This is the time of year where cold
winter air likes entering the house through openings down low, while that
nice warm air likes to escape up high and it creates lovely items like
ice-dams. While this will not eliminate that issue, it can help slow it
down. Then of course, there is always the warm toes & comfort reasons…

Preferred Pest Termite and Turf offers
ATMOX ventilated crawl space systems and this system automatically closes and
opens to allow the right amount of moisture to prevent any problems. ATMOX
takes a common sense approach: Only ventilate with outside air when it
is beneficial to the crawlspace. So see what’s best for your crawl
space and call Preferred Pest at (865) 234-4008 today to schedule a
